I ripped off the plastic casing because it appeared that some wire insulation was falling off and the wires very close to touching, rewrapped it with ducttape, checked its voltage, .5 volts, put it on my charger at ~.75 amp hour, and it finished charging withen 20 minutes(should have taken two hours), and checked the voltage,it read 8.06 volts, seems very strange.....

I then switched over to amps and it measuered 1.5 amps, steadily dropped and I then stopped at .4 amps, switched back to volts, and the battery steadily rose from 5 volts to 6.6 volts when i stopped measuring, this battery is magic.....

All hail Rodney, the holy 555 timerAnd Steve said: "Let there be lead!"

The voltage on a battery isn't fixed. When it says 6V rating, that doesn't mean it is ever actually 6V. As a battery is drained, the voltage drops too.

The voltage is dependent on the internal charge level (measured in mAh). A battery that can't hold a charge (which effectively has a low mAh), will drop in voltage much faster.

I know some types of lead acid batteries can be 'saved' by charging and discharging it a few times (its a chemistry thing, too lazy to explain). NiCads however I'm not sure . . . worth looking up, or experimenting to find out . . . but I think your battery is dead . . .

It will be pretty obvious which one it is. VERY good batteries might have around 2 aH, or 2000 mAH. If yours is not in the decimal places, it is being measured in mAH. Also, next time grab some niMH batteries so that you don't have to worry about the memory effect of niCads.
